A shed is a pretty easy build if you can get the materials out there. you can get one together in a day if everything is there. i havent read enough to know your climate but if it's deserty like here, where it gets crazy hot in the summer... I would strongly suggest not getting a metal one, they turn into ovens. its like 150 degrees or more in mine in the summer, even with the whole front open. When i can i'm replacing it with just stick built. mine would seriously work better as a huge dehydrator lol

A driveway is a big deal. I'm rooting for you to get that put in. We have been working on ours for 5 years now by hand lol.
